Remove new line character in C

Question

I am trying to use getc(character) to take an element from a file and do stuff with it, but it appears that it must have a '\n' before the end of a line is met.

How can I remove this so that when I copy the characters I don't have a new line charachter appearing anywhere - thus allowing me to deal with printing new lines when I choose?

Answer 1

You could replace it with a null terminator.

Here is one (simple) way to do it off the top of my head:

 mystr[ strlen(mystr) - 1 ] = '\0';

Answer 2

Supposing that buf is of type char and it holds the string value read in from the file...

buf[strlen(buf)-1] = '\0';

That sets the second-last character of the buffer to nul i.e. '\0' in order to remove the new-line character.

Edit: Since loz mentioned a compiler error I suspect it's a const char * is used...Can we see the code please...

Answer 3

.
.
.
#include <string.h>
.
. /* insert stuff here */
.
char* mystring = "THIS IS MY STRING\n"
char* deststring;
.
.
.
strncpy(deststring, mystring, strlen(mystring)-1);
.
.
.

(As an added note, I'm not a huge fan of dropping \0 characters in strings like that. It doesn't work well when you start doing i18n and the character width is not fixed. UTF-8, for example, can use anywhere from 1 to 4 bytes per "character".)

Answer 4

Hmm, wouldn't help to use getc to fill a buffer and remove newline and carriage return characters?
